Updated to iTunes 12.1, now iTunes crashes every time it attempts to access the internet through our internal proxy - cannot access store!

Thanks for that, tt2.

We're not in a position to test it either yet, as it could cause disruption, however tonight when nobody is using the systems, I'll update iTunes on a test PC and remove the firewall block on iTunes. I will update this with what happens. Hopefully Apple pulled their fingers out... find out after the break!

Argh, it's still not working.

It isn't crashing anymore but iTunes freezes completely when it tries to access the internet. The only way to get out of it is to use task manager to terminate process.

So, unsuprisingly, not fixed! Looks like they did make an effort though.

EDIT:

Do I actually have to completely uninstall iTunes (and all Apple-related software) for this to work? I just used "Apple Software Update" to update it to version 12.4.

Did you try a fresh install or update it via "Apple Software Update"?

It's still not working for me even after completely uninstalling all Apple software. Heck, I even tried on a fresh Windows 7 install in a virtual machine!

It doesn't crash in the same manner as iTunes 12.3.3 (which was instant, and always reproducible), but after a proportionate amount of testing, I have found that it seems to follow 3 possible outcomes...

• iTunes starts up and asks for proxy authentication.
• After authenticating, iTunes appears to be functioning normally... until you try to go to the store, or close iTunes.
  • Attempting to close iTunes will cause iTunes to freeze entirely and you'll need to use task manager to terminate the process.
  • Going to the store will either:
    • Crash in module "W T F.dll" (Apple sure got that right, *** is this crap?). This might not happen immediately, and iTunes may appear frozen for a short while before crashing in this manner.
    • Freeze the store page only. iTunes will continue to function as a media player, until you attempt to close iTunes.
    • Freeze iTunes entirely and you'll need to use task manager to terminate the process.

Screenshot specially prepared for those of you who don't believe me...

Anybody got any other ideas I can try? Thanks.

Also, on a slightly unrelated note, I forgot to mention this (too late to edit my post), but the first time I opened iTunes since updating it to 12.4, it completely blanked my iTunes library, but as a system administrator, luckily I had a backup of the iTunesLibrary.itl file from a few days ago, so restoring the library was trivial.

Make sure you back up your library before upgrading!!

Hey, thanks for that, I didn't know iTunes takes backups of your library automatically, I restored my iTunes Library.itl file through Windows Server Backup (everyone stores their library on a network share which is backed up weekly by our server), so it was just a matter of using Windows Previous Versions to restore the most recent one.

But it's useful for non-network users (or the majority of home users who don't ever seem to do backups), I suppose. It doesn't do it as often, (my latest automatic iTunes library backup was March 2016), but I suppose if you're really stuck, it's something.

iTunes has never blanked my library before, and I've been using it since 2007, when I got my first ever iPod Nano 1st Generation! Ahh, the memories...
